GFORD, or SAME rLAo IMPROVEMENT IN WINDMILLS'Q Specification forming part of Letters Patent No. 164,719, dated September 1, 1874 applicatinn filed April 2511874."

To all whom it may concern Be it known-that I, JACOB L'. RUST, of Mil-.

.lersbur'g, in the county of Mercer and State of Fig, 2, a sectional side elevation, and .Fig'. 3 atop view, of thesame.

Similar letters of reference indicate corresponding parts.

and tlieirpointed out in, the claim.

i In the drawin g, A represents a strong frame,

made of vertical side pillars with top connecting-piece,'froni which the main pivot-bolt'a is centrally suspended. The wheel-supporting frame B is hung to pivot-bolt a, and turns freely thereon, being also made of sufficient "strength for the ,wheel; Frame B carries in suitable bearings at its lowermost points the horizontal shaft b of wheel 0, transmitting,

by means of crank or'eccentric d and pitman and swivel-point e, the motive power of the Wheel to the gearing below for pumping or other work, in whatever position the wheel. may be, as the swivel-joint connection allows the ready turning of the pitnian with the wheel. Wheel (1 is constructed of strong diagonal main wings, j, placed under-right angles to each other, to which the intermediate wings are rigidly connected under the required angle by means of wire rope f, or in other suitable manner, as indicated in Fig. 1. To the upper or top part of wheel- 'supporting frame Bis firmly attached, underrightangles' thereto and'parallel to the plane ot'wheel C, a small sid vane, I), while the main vane E is hung to pivot-bolt a. A cord or chain, 9, passes from. some point near the and over a pulley, g, of :the side vane'I) as desired.

in a simple and very effective manner.

to the upper beam of main vane E, and serves to regulate the speed of the wheelfrom below, A second cord, h', is attached to the front part of wheelframe,-passes then over a pulley, h, at the end of the forwardextended lower beam of main vane it, over a second pulley, W, of the same, and is provided with a weight, It, which is. proportioned to the size of the wheel, and to a fixed degree of the Wind; a p

The regulating device begins to operate when the'wind-strikes the face of-thewheel and side vane With'such force that the action The invention will first be fullydescribed,

of the weight on the same is overcome, throwing thereby the wheel back toward the main vane The greater the power of the wind the smaller becomes the angle between the wheel and the main vane, till the same assumes at last a position -parallel to the wheel. The wheel turns thereby more and more the outer edge of its wings toward the wind, sothat its effect on the-wheel is not increased,"but the speed of the wheel kept up at a regular rate. When the wind diminishes the weight carries the main vane gradually back in its old position, regulating thus the speed of the wheel t of wheel-supporting frame B define the extent of motion. of the main vane E, and give the necessary stability to it when in vertical or parallel position towheel 0.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 7 As an improvement in windmills, the wheel G and wheelrsu'pporting frame Bfpivoted to a vertical bolt,-a., and suspended from a top frame, A, substantially in the manner and for the purpose set'forth.
